Work has been carried out recently, which demonstrates misorientation measurements
recorded by using electron backscatter diffraction (EBSD) enables one to undertake local post
mortem plastic strain quantification once the degree of misorientation is calibrated against plastic
strain. The present paper builds on this work and investigates the possibility of determining strain in
individual grains. Due to the anisotropy of crystalline grains, polycrystalline material deform
inhomogeneously on a microstructural level. In this study, the local strain induced in a pure copper
specimen during tensile loading measured using EBSD was compared to in-situ strain
measurements using optical microscopy imaging in conjunction with image correlation technique.
By applying an averaging procedure for improving the accuracy of the measured EBSD data, the
distribution of the misorientation within grains was quantified, and, as one would expect, it tended
to be highest near the grain boundaries.
